Installing extra Lan Card

[Alan]

Hi all,

I am trying to network two computers to my Linux computer.
(a Win2000 machine and a Windows 98 Notebook).

I have installed another Lan card into my Linux machine.
I am using manual IP addresses.
eth0         =  192.168.0.1       (255.255.255.0)
Win2000 = 192.168.0.2
Laptop    = 192.168.0.3
eth1        =  192.168.0.4

Basically I don't know what I am doing so would appreciate some help.
- I have configured 'eth1' using 'linux-conf' utility.
However I can't ping 192.168.0.4 from anywhere (even on the linux machine).

Any ideas ?

Alan.
